Plot: After many centuries of disciplined training in Taoism whilst living in a cave on Mount Emei, the protagonist Bai Su Zhen, with the help of a heavenly immortality pill, transforms herself from her original form as a snake into human form, en route to seek immortality on her quest for divinity, guided by the Mother of Mercy, Guan Yin. She then meets and defeats Xiao Qing ("Small Green") in combat, and chose mercy rather than ending Xiao Qing’s life
